Q. What do you understand by magnetic effect of electric current? Ans: The phenomenon due to which, a wire behaves like a magnet when electric current is passed through it, is called as the magnetic effect of electric current. Q. What is magnetic field?  Ans: The region around the magnet, where force of attraction or repulsion can be felt by magnetic materials, is called as magnetic field. Q. Why does a compass needle get deflected when brought near a bar magnet ? Ans: The magnet exerts its influence in the region surrounding it.So, the compass needle shows deflection when brought near a magnet or an electromagnet. Q. Why two magnetic field lines do not intersect each other? Ans: The magnetic field lines the magnetic field lines form closed curves and originate in fix direction inside and out side magnet so magnetic field lines do not intersect each other. Q. What happens to the deflection of the compass needle placed at a given point if the current in the straight copper w...
